JBL 6020

Name: JBL 6020
Brand: JBL

Documentation on the JBL 6020 is thin, and the record is ambiguous. The name "6020" shows up in two places: a passing mention in a Stereonomono article about satellite/subwoofer systems, and a fuller specification list from the German site Hifi-Wert. That second source spells it "P6020" and places it in JBL's Performance Series. No source settles whether these are the same product or two different models.

Here is what the record shows, attributed to the "JBL P6020" / "P-6020". It's a powered subwoofer, bass-reflex design, with a 30 cm driver and a 300-watt RMS amplifier (600 watts peak). The Hifi-Wert spec sheet lists a frequency response of 23-200 Hz, a signal-to-noise ratio above 85 dB, an adjustable crossover from 50-150 Hz, and a 0/180° phase switch. Power consumption is given as 550 watts. The enclosure measures 38.5 × 46.5 × 40 cm (W × H × D) and weighs 14.5 kg. Input and output are both line level, and impedance is 8 ohms.

That's all there is. No production years, no original price, no reviews, and no second independent source. Every spec above traces back to that single Hifi-Wert listing. HiFI-Stereo (April 1992, p.81) covered JBL's separates around this era, but it has no period review of the 6020 itself.
